Everton held a poor record against the Premier League's 'big six' sides before beating Chelsea 2-0 at Goodison Park last month.

Victories over Arsenal and United have subsequently followed and Silva says the onus is on ensuring such wins become the norm.

"It's not about next [season], we have to keep looking for this season, we have our goal to achieve," he added when asked what the win will do for confidence next term.

"Since the first day we have changed nothing about our goal, we have to keep fighting to prove our quality every single match.

"Before Chelsea we didn't win our last 26 versus this type of team, I said to you here in this press conference when you ask what this means – the first thing I said was we have to do everything again to make sure we are not many [games without a win again] against these teams.

"It's important for us to keep this run, finish the season in a good spot, it will be very good for us to prepare next season but we have too many things to keep fighting for in this season to start talking about the next."

The result saw Everton climb to seventh in the table, having finished eighth last season.
